What are non-nutritive additives in animal feed?

• A. Substances like antibiotics, preservatives, and flavors added to improve health and feed handling.
• B. Vitamins and minerals only
• C. Water and fiber
• D. Seeds and grains

Answer: (A)

Non-nutritive additives are substances added to feed that don’t provide energy or direct nutrients themselves, but serve other important roles such as supporting health, improving feed stability, or enhancing intake. For example, antibiotics can help manage disease and may influence growth, preservatives protect feed from spoilage and extend shelf life, and flavors make the feed more palatable so animals eat enough. These functions are different from nutritive additives like vitamins and minerals, which are nutrients the animal needs for metabolism. Water and fiber are parts of the diet, and seeds and grains are ingredients rather than additives. So the described group—antibiotics, preservatives, and flavors—fits non-nutritive additives.
